2. BACKGROUND OF THE INVENTION

Obesity, hyperlipidemia, and diabetes have been shown to play a causalrole in atherosclerotic cardiovascular diseases, which currently accountfor a considerable proportion of morbidity in Western society. Further,one human disease, termed “Syndrome X” or “Metabolic Syndrome”, ismanifested by defective glucose metabolism (insulin resistance),elevated blood pressure (hypertension), and a blood lipid imbalance(dyslipidemia). See e.g. Reaven, 1993, Annu. Rev. Med. 44:121–131.

The evidence linking elevated serum cholesterol to coronary heartdisease is overwhelming. Circulating cholesterol is carried by plasmalipoproteins, which are particles of complex lipid and proteincomposition that transport lipids in the blood. Low density lipoprotein(LDL) and high density lipoprotein (HDL) are the majorcholesterol-carrier proteins. LDL is believed to be responsible for thedelivery of cholesterol from the liver, where it is synthesized orobtained from dietary sources, to extrahepatic tissues in the body. Theterm “reverse cholesterol transport” describes the transport ofcholesterol from extrahepatic tissues to the liver, where it iscatabolized and eliminated. It is believed that plasma HDL particlesplay a major role in the reverse transport process, acting as scavengersof tissue cholesterol. HDL is also responsible for the removal ofnon-cholesterol lipid, oxidized cholesterol and other oxidized productsfrom the bloodstream.

Atherosclerosis, for example, is a slowly progressive diseasecharacterized by the accumulation of cholesterol within the arterialwall. Compelling evidence supports the belief that lipids deposited inatherosclerotic lesions are derived primarily from plasma apolipoproteinB (apo B)-containing lipoproteins, which include chylomicrons, very lowdensity lipoproteins (VLDL), intermediate-density lipoproteins (IDL),and LDL. The apo B-containing lipoprotein, and in particular LDL, haspopularly become known as the “bad” cholesterol. In contrast, HDL serumlevels correlate inversely with coronary heart disease. Indeed, highserum levels of HDL are regarded as a negative risk factor. It ishypothesized that high levels of plasma HDL are not only protectiveagainst coronary artery disease, but may actually induce regression ofatherosclerotic plaque (e.g., see Badimon et al., 1992, Circulation86:(Suppl. III)86–94; Dansky and Fisher, 1999, Circulation 100:1762 3.).Thus, HDL has popularly become known as the “good” cholesterol.

2.1 Cholesterol Transport

The fat-transport system can be divided into two pathways: an exogenousone for cholesterol and triglycerides absorbed from the intestine and anendogenous one for cholesterol and triglycerides entering thebloodstream from the liver and other non-hepatic tissue.

In the exogenous pathway, dietary fats are packaged into lipoproteinparticles called chylomicrons, which enter the bloodstream and delivertheir triglycerides to adipose tissue for storage and to muscle foroxidation to supply energy. The remnant of the chylomicron, whichcontains cholesteryl esters, is removed from the circulation by aspecific receptor found only on liver cells. This cholesterol thenbecomes available again for cellular metabolism or for recycling toextrahepatic tissues as plasma lipoproteins.

In the endogenous pathway, the liver secretes a large, very-low-densitylipoprotein particle (VLDL) into the bloodstream. The core of VLDLconsists mostly of triglycerides synthesized in the liver, with asmaller amount of cholesteryl esters either synthesized in the liver orrecycled from chylomicrons. Two predominant proteins are displayed onthe surface of VLDL, apolipoprotein B-100 (apo B-100) and apolipoproteinE (apo E), although other apolipoproteins are present, such asapolipoprotein CIII (apo CIII) and apolipoprotein CII (apo CII). WhenVLDL reaches the capillaries of adipose tissue or of muscle, itstriglyceride is extracted. This results in the formation of a new kindof particle called intermediate-density lipoprotein (IDL) or VLDLremnant, decreased in size and enriched in cholesteryl esters relativeto a VLDL, but retaining its two apoproteins.

In human beings, about half of the IDL particles are removed from thecirculation quickly, generally within two to six hours of theirformation. This is because IDL particles bind tightly to liver cells,which extract IDL cholesterol to make new VLDL and bile acids. The IDLnot taken up by the liver is catabolized by the hepatic lipase, anenzyme bound to the proteoglycan on liver cells. Apo E dissociates fromIDL as it is transformed to LDL. Apo B-100 is the sole protein of LDL.

Primarily, the liver takes up and degrades circulating cholesterol tobile acids, which are the end products of cholesterol metabolism. Theuptake of cholesterol-containing particles is mediated by LDL receptors,which are present in high concentrations on hepatocytes. The LDLreceptor binds both apo E and apo B-100 and is responsible for bindingand removing both IDL and LDL from the circulation. In addition, remnantreceptors are responsible for clearing chylomicrons and VLDL remnants(i.e., IDL). However, the affinity of apo E for the LDL receptor isgreater than that of apo B-100. As a result, the LDL particles have amuch longer circulating life span than IDL particles; LDL circulates foran average of two and a half days before binding to the LDL receptors inthe liver and other tissues. High serum levels of LDL, the “bad”cholesterol, are positively associated with coronary heart disease. Forexample, in atherosclerosis, cholesterol derived from circulating LDLaccumulates in the walls of arteries. This accumulation forms bulkyplaques that inhibit the flow of blood until a clot eventually forms,obstructing an artery and causing a heart attack or stroke.

Ultimately, the amount of intracellular cholesterol liberated from theLDL controls cellular cholesterol metabolism. The accumulation ofcellular cholesterol derived from VLDL and LDL controls three processes.First, it reduces the ability of the cell to make its own cholesterol byturning off the synthesis of HMGCoA reductase, a key enzyme in thecholesterol biosynthetic pathway. Second, the incoming LDL-derivedcholesterol promotes storage of cholesterol by the action of cholesterolacyltransferase (“ACAT”), the cellular enzyme that converts cholesterolinto cholesteryl esters that are deposited in storage droplets. Third,the accumulation of cholesterol within the cell drives a feedbackmechanism that inhibits cellular synthesis of new LDL receptors. Cells,therefore, adjust their complement of LDL receptors so that enoughcholesterol is brought in to meet their metabolic needs, withoutoverloading (for a review, see Brown & Goldstein, in The PharmacologicalBasis Of Therapeutics, 8th Ed., Goodman & Gilman, Pergamon Press, NewYork, 1990, Ch. 36, pp. 874–896).

High levels of apo B-containing lipoproteins can be trapped in thesubendothelial space of an artery and undergo oxidation. The oxidizedlipoprotein is recognized by scavenger receptors on macrophages. Bindingof oxidized lipoprotein to the scavenger receptors can enrich themacrophages with cholesterol and cholesteryl esters independently of theLDL receptor. Macrophages can also produce cholesteryl esters by theaction of ACAT. LDL can also be complexed to a high molecular weightglycoprotein called apolipoprotein(a), also known as apo(a), through adisulfide bridge. The LDL-apo(a) complex is known as Lipoprotein(a) orLp(a). Elevated levels of Lp(a) are detrimental, having been associatedwith atherosclerosis, coronary heart disease, myocardial infarction,stroke, cerebral infarction, and restenosis following angioplasty.

2.2 Reverse Cholesterol Transport

Peripheral (non-hepatic) cells predominantly obtain their cholesterolfrom a combination of local synthesis and uptake of preformed sterolfrom VLDL and LDL. Cells expressing scavenger receptors, such asmacrophages and smooth muscle cells, can also obtain cholesterol fromoxidized apo B-containing lipoproteins. In contrast, reverse cholesteroltransport (RCT) is the pathway by which peripheral cell cholesterol canbe returned to the liver for recycling to extrahepatic tissues, hepaticstorage, or excretion into the intestine in bile. The RCT pathwayrepresents the only means of eliminating cholesterol from mostextrahepatic tissues and is crucial to the maintenance of the structureand function of most cells in the body.

The enzyme in blood involved in the RCT pathway, lecithin:cholesterolacyltransferase (LCAT), converts cell-derived cholesterol to cholesterylesters, which are sequestered in HDL destined for removal. LCAT isproduced mainly in the liver and circulates in plasma associated withthe HDL fraction. Cholesterol ester transfer protein (CETP) and anotherlipid transfer protein, phospholipid transfer protein (PLTP), contributeto further remodeling the circulating HDL population (see for exampleBruce et al., 1998, Annu. Rev. Nutr. 18:297 330). PLTP supplies lecithinto HDL, and CETP can move cholesteryl esters made by LCAT to otherlipoproteins, particularly apoB-containing lipoproteins, such as VLDL.HDL triglycerides can be catabolized by the extracellular hepatictriglyceride lipase, and lipoprotein cholesterol is removed by the livervia several mechanisms.

Each HDL particle contains at least one molecule, and usually two tofour molecules, of apolipoprotein A I (apo A I). Apo A I is synthesizedby the liver and small intestine as preproapolipoprotein, which issecreted as a proprotein that is rapidly cleaved to generate a maturepolypeptide having 243 amino acid residues. Apo A I consists mainly of a22 amino acid repeating segment, spaced with helix-breaking prolineresidues. Apo A I forms three types of stable structures with lipids:small, lipid-poor complexes referred to as pre-beta-1 HDL; flatteneddiscoidal particles, referred to as pre-beta-2 HDL, which contain onlypolar lipids (e.g., phospholipid and cholesterol); and sphericalparticles containing both polar and nonpolar lipids, referred to asspherical or mature HDL (HDL3 and HDL2). Most HDL in the circulatingpopulation contains both apo A I and apo A II, a second major HDLprotein. This apo A I- and apo A II-containing fraction is referred toherein as the AI/AII-HDL fraction of HDL. But the fraction of HDLcontaining only apo A I, referred to herein as the AI HDL fraction,appears to be more effective in RCT. Certain epidemiologic studiessupport the hypothesis that the Al-HDL fraction is antiartherogenic(Parra et al., 1992, Arterioscler. Thromb. 12:701–707; Decossin et al.,1997, Eur. J. Clin. Invest. 27:299–307).

Although the mechanism for cholesterol transfer from the cell surface isunknown, it is believed that the lipid-poor complex, pre-beta-1 HDL, isthe preferred acceptor for cholesterol transferred from peripheraltissue involved in RCT. Cholesterol newly transferred to pre-beta-1 HDLfrom the cell surface rapidly appears in the discoidal pre-beta-2 HDL.PLTP may increase the rate of disc formation (Lagrost et al., 1996, J.Biol. Chem. 271:19058–19065), but data indicating a role for PLTP in RCTis lacking. LCAT reacts preferentially with discoidal and spherical HDL,transferring the 2-acyl group of lecithin or phosphatidylethanolamine tothe free hydroxyl residue of fatty alcohols, particularly cholesterol,to generate cholesteryl esters (retained in the HDL) and lysolecithin.The LCAT reaction requires an apolipoprotein such as apo A I or apo A-IVas an activator. ApoA-I is one of the natural cofactors for LCAT. Theconversion of cholesterol to its HDL-sequestered ester prevents re-entryof cholesterol into the cell, resulting in the ultimate removal ofcellular cholesterol. Cholesteryl esters in the mature HDL particles ofthe AI-HDL fraction are removed by the liver and processed into bilemore effectively than those derived from the AI/AII-HDL fraction. Thismay be due, in part, to the more effective binding of AI-HDL to thehepatocyte membrane. Several HDL receptors have been identified, themost well characterized of which is the scavenger receptor class B, typeI (SR BI) (Acton et al., 1996, Science 271:518–520). The SR-BI isexpressed most abundantly in steroidogenic tissues (e.g., the adrenals),and in the liver (Landshulz et al., 1996, J. Clin. Invest. 98:984–995;Rigotti et al., 1996, J. Biol. Chem. 271:33545–33549). Other proposedHDL receptors include HB1 and HB2 (Hidaka and Fidge, 1992, Biochem J.15:161 7; Kurata et al., 1998, J. Atherosclerosis and Thrombosis 4:1127).

While there is a consensus that CETP is involved in the metabolism ofVLDL- and LDL-derived lipids, its role in RCT remains controversial.However, changes in CETP activity or its acceptors, VLDL and LDL, play arole in “remodeling” the HDL population. For example, in the absence ofCETP, the HDL becomes enlarged particles that are poorly removed fromthe circulation (for reviews on RCT and HDL, See Fielding & Fielding,1995, J. Lipid Res. 36:211–228; Barrans et al., 1996, Biochem. Biophys.Acta. 1300:73–85; Hirano et al., 1997, Arterioscler. Thromb. Vasc. Biol.17:1053–1059).

2.3 Reverse Transport of Other Lipids

HDL is not only involved in the reverse transport of cholesterol, butalso plays a role in the reverse transport of other lipids, i.e., thetransport of lipids from cells, organs, and tissues to the liver forcatabolism and excretion. Such lipids include sphingomyelin, oxidizedlipids, and lysophophatidylcholine. For example, Robins and Fasulo(1997, J. Clin. Invest. 99:380 384) have shown that HDL stimulates thetransport of plant sterol by the liver into bile secretions.

2.4 Peroxisome Proliferator Activated Receptor Pathway

Peroxisome proliferators are a structurally diverse group of compoundsthat, when administered to rodents, elicit dramatic increases in thesize and number of hepatic and renal peroxisomes, as well as concomitantincreases in the capacity of peroxisomes to metabolize fatty acids viaincreased expression of the enzymes required for the β-oxidation cycle(Lazarow and Fujiki, 1985, Ann. Rev. Cell Biol. 1:489 530; Vamecq andDraye, 1989, Essays Biochem. 24:1115 225; and Nelali et al., 1988,Cancer Res. 48:5316 5324). Chemicals included in this group are thefibrate class of hypolipidemic drugs, herbicides, and phthalateplasticizers (Reddy and Lalwani, 1983, Crit. Rev. Toxicol. 12:1 58).Peroxisome proliferation can also be elicited by dietary orphysiological factors, such as a high fat diet and cold acclimatization.

Insight into the mechanism whereby peroxisome proliferators exert theirpleiotropic effects was provided by the identification of a member ofthe nuclear hormone receptor superfamily activated by these chemicals(Isseman and Green, 1990, Nature 347:645 650). This receptor, termedperoxisome proliferator activated receptor α (PPARα), was subsequentlyshown to be activated by a variety of medium and long chain fatty acids.PPARα activates transcription by binding to DNA sequence elements,termed peroxisome proliferator response elements (PPRE), in the form ofa heterodimer with the retinoid X receptor (RXR). RXR is activated by9-cis retinoic acid (see Kliewer et al., 1992, Nature 358:771 774;Gearing et al., 1993, Proc. Natl. Acad. Sci. USA 90:1440 1444, Keller etal., 1993, Proc. Natl. Acad. Sci. USA 90:2160 2164; Heyman et al., 1992,Cell 68:397 406, and Levin et al., 1992, Nature 355:359 361). Since thediscovery of PPARα, additional isoforms of PPAR have been identified,e.g., PPARβ, PPARγ and PPARδ, which have similar functions and aresimilarly regulated.

PPARs have been identified in the enhancers of a number of gene-encodingproteins that regulate lipid metabolism. These proteins include thethree enzymes required for peroxisomal β-oxidation of fatty acids;apolipoprotein A-I; medium chain acyl-CoA dehydrogenase, a key enzyme inmitochondrial β-oxidation; and aP2, a lipid binding protein expressedexclusively in adipocytes (reviewed in Keller and Whali, 1993, TEM,4:291 296; see also Staels and Auwerx, 1998, Atherosclerosis 137Suppl:S19 23). The nature of the PPAR target genes coupled with theactivation of PPARs by fatty acids and hypolipidemic drugs suggests aphysiological role for the PPARs in lipid homeostasis.

Pioglitazone, an antidiabetic compound of the thiazolidinedione class,was reported to stimulate expression of a chimeric gene containing theenhancer/promoter of the lipid binding protein aP2 upstream of thechloroamphenicol acetyl transferase reporter gene (Harris and Kletzien,1994, Mol. Pharmacol. 45:439 445). Deletion analysis led to theidentification of an approximately 30 bp region accounting forpioglitazone responsiveness. In an independent study, this 30 bpfragment was shown to contain a PPRE (Tontonoz et al.,1994, NucleicAcids Res. 22:5628 5634). Taken together, these studies suggested thepossibility that the thiazolidinediones modulate gene expression at thetranscriptional level through interactions with a PPAR and reinforce theconcept of the interrelatedness of glucose and lipid metabolism.

2.5 Current Cholesterol Management Therapies

In the past two decades or so, the segregation of cholesterolemiccompounds into HDL and LDL regulators and recognition of thedesirability of decreasing blood levels of the latter has led to thedevelopment of a number of drugs. However, many of these drugs haveundesirable side effects and/or are contraindicated in certain patients,particularly when administered in combination with other drugs.

Bile-acid-binding resins are a class of drugs that interrupt therecycling of bile acids from the intestine to the liver. Examples ofbile-acid-binding resins are cholestyramine (QUESTRAN LIGHT,Bristol-Myers Squibb), and colestipol hydrochloride (COLESTID, Pharmacia& Upjohn Company). When taken orally, these positively charged resinsbind to negatively charged bile acids in the intestine. Because theresins cannot be absorbed from the intestine, they are excreted,carrying the bile acids with them. The use of such resins, however, atbest only lowers serum cholesterol levels by about 20%. Moreover, theiruse is associated with gastrointestinal side-effects, includingconstipation and certain vitamin deficiencies. Moreover, since theresins bind to drugs, other oral medications must be taken at least onehour before or four to six hours subsequent to ingestion of the resin,complicating heart patients' drug regimens.

The statins are inhibitors of cholesterol synthesis. Sometimes, thestatins are used in combination therapy with bile-acid-binding resins.Lovastatin (MEVACOR, Merck & Co., Inc.), a natural product derived froma strain of Aspergillus; pravastatin (PRAVACHOL, Bristol-Myers SquibbCo.); and atorvastatin (LIPITOR, Warner Lambert) block cholesterolsynthesis by inhibiting HMGCoA reductase, the key enzyme involved in thecholesterol biosynthetic pathway. Lovastatin significantly reduces serumcholesterol and LDL-serum levels. However, serum HDL levels are onlyslightly increased following lovastatin administration. The mechanism ofthe LDL-lowering effect may involve both reduction of VLDL concentrationand induction of cellular expression of LDL-receptor, leading to reducedproduction and/or increased catabolism of LDL. Side effects, includingliver and kidney dysfunction are associated with the use of these drugs.

Nicotinic acid, also known as niacin, is a water-soluble vitaminB-complex used as a dietary supplement and antihyperlipidemic agent.Niacin diminishes the production of VLDL and is effective at loweringLDL. It is used in combination with bile-acid-binding resins. Niacin canincrease HDL when administered at therapeutically effective doses;however, its usefulness is limited by serious side effects.

Fibrates are a class of lipid-lowering drugs used to treat various formsof hyperlipidemia, elevated serum triglycerides, which may also beassociated with hypercholesterolemia. Fibrates appear to reduce the VLDLfraction and modestly increase HDL; however, the effects of these drugson serum cholesterol is variable. In the United States, fibrates havebeen approved for use as antilipidemic drugs, but have not receivedapproval as hypercholesterolemia agents. For example, clofibrate(ATROMID-S, Wyeth-Ayerst Laboratories) is an antilipidemic agent thatacts to lower serum triglycerides by reducing the VLDL fraction.Although ATROMID-S may reduce serum cholesterol levels in certainpatient subpopulations, the biochemical response to the drug isvariable, and is not always possible to predict which patients willobtain favorable results. ATROMID-S has not been shown to be effectivefor prevention of coronary heart disease. The chemically andpharmacologically related drug, gemfibrozil (LOPID, Parke-Davis), is alipid regulating agent which moderately decreases serum triglyceridesand VLDL cholesterol. LOPID also increases HDL cholesterol, particularlythe HDL2 and HDL3 subfractions, as well as both the AI/AII-HDLfractions. However, the lipid response to LOPID is heterogeneous,especially among different patient populations. Moreover, whileprevention of coronary heart disease was observed in male patientsbetween the ages of 40 and 55 without history or symptoms of existingcoronary heart disease, it is not clear to what extent these findingscan be extrapolated to other patient populations (e.g., women, older andyounger males). Indeed, no efficacy was observed in patients withestablished coronary heart disease. Serious side-effects are associatedwith the use of fibrates, including toxicity; malignancy, particularlymalignancy of gastrointestinal cancer; gallbladder disease; and anincreased incidence in non-coronary mortality. These drugs are notindicated for the treatment of patients with high LDL or low HDL astheir only lipid abnormality.

Oral estrogen replacement therapy may be considered for moderatehypercholesterolemia in post-menopausal women. However, increases in HDLmay be accompanied with an increase in triglycerides. Estrogen treatmentis, of course, limited to a specific patient population, postmenopausalwomen, and is associated with serious side effects, including inductionof malignant neoplasms; gall bladder disease; thromboembolic disease;hepatic adenoma; elevated blood pressure; glucose intolerance; andhypercalcemia.

Long chain carboxylic acids, particularly long chain α,ω-dicarboxylicacids with distinctive substitution patterns, and their simplederivatives and salts, have been disclosed for treating atherosclerosis,obesity, and diabetes (See, e.g., Bisgaier et al., 1998, J. Lipid Res.39:17–30, and references cited therein; International Patent PublicationWO 98/30530; U.S. Pat. No. 4,689,344; International Patent PublicationWO 99/00116; and U.S. Pat. No. 5,756,344). However, some of thesecompounds, for example the α,ω-dicarboxylic acids substituted at theirα,α′-carbons (U.S. Pat. No. 3,773,946), while having serum triglycerideand serum cholesterol-lowering activities, have no value for treatmentof obesity and hypercholesterolemia (U.S. Pat. No. 4,689,344).

U.S. Pat. No. 4,689,344 disclosesβ,β,β′,β′-tetrasubstituted-α,ω-alkanedioic acids that are optionallysubstituted at their α,α,α′,α′-positions, and alleges that they areuseful for treating obesity, hyperlipidemia, and diabetes. According tothis reference, both triglycerides and cholesterol are loweredsignificantly by compounds such as3,3,14,14-tetramethylhexadecane-1,16-dioic acid. U.S. Pat. No. 4,689,344further discloses that the β,β,β′,β′-tetramethyl-alkanediols of U.S.Pat. No. 3,930,024 also are not useful for treating hypercholesterolemiaor obesity.

Other compounds are disclosed in U.S. Pat. No. 4,711,896. In U.S. Pat.No. 5,756,544, α,ω-dicarboxylic acid-terminated dialkane ethers aredisclosed to have activity in lowering certain plasma lipids, includingLp(a), triglycerides, VLDL-cholesterol, and LDL-cholesterol, in animals,and elevating others, such as HDL-cholesterol. The compounds are alsostated to increase insulin sensitivity. In U.S. Pat. No. 4,613,593,phosphates of dolichol, a polyprenol isolated from swine liver, arestated to be useful in regenerating liver tissue, and in treatinghyperuricuria, hyperlipemia, diabetes, and hepatic diseases in general.

U.S. Pat. No. 4,287,200 discloses azolidinedione derivatives withanti-diabetic, hypolipidemic, and anti-hypertensive properties. However,the administration of these compounds to patients can produce sideeffects such as bone marrow depression, and both liver and cardiaccytotoxicity. Further, the compounds disclosed by U.S. Pat. No.4,287,200 stimulate weight gain in obese patients.

It is clear that none of the commercially available cholesterolmanagement drugs has a general utility in regulating lipid, lipoprotein,insulin and glucose levels in the blood. Thus, compounds that have oneor more of these utilities are clearly needed. Further, there is a clearneed to develop safer drugs that are efficacious at lowering serumcholesterol, increasing HDL serum levels, preventing coronary heartdisease, and/or treating existing disease such as atherosclerosis,obesity, diabetes, and other diseases that are affected by lipidmetabolism and/or lipid levels. There is also a clear need to developdrugs that may be used with other lipid-altering treatment regimens in asynergistic manner. There is still a further need to provide usefultherapeutic agents whose solubility and Hydrophile/Lipophile Balance(HLB) can be readily varied.

The present compositions will contain a therapeutically effective amountof a compound of the invention, optionally more than one compound of theinvention, preferably in purified form, together with a suitable amountof a pharmaceutically acceptable vehicle so as to provide the form forproper administration to the patient.

In a specific embodiment, the term “pharmaceutically acceptable” meansapproved by a regulatory agency of the Federal or a state government orlisted in the U.S. Pharmacopeia or other generally recognizedpharmacopeia for use in animals, and more particularly in humans. Theterm “vehicle” refers to a diluent, adjuvant, excipient, or carrier withwhich a compound of the invention is administered. Such pharmaceuticalvehicles can be liquids, such as water and oils, including those ofpetroleum, animal, vegetable or synthetic origin, such as peanut oil,soybean oil, mineral oil, sesame oil and the like. The pharmaceuticalvehicles can be saline, gum acacia, gelatin, starch paste, talc,keratin, colloidal silica, urea, and the like. In addition, auxiliary,stabilizing, thickening, lubricating and coloring agents may be used.When administered to a patient, the compounds and compositions of theinvention and pharmaceutically acceptable vehicles are preferablysterile. Water is a preferred vehicle when the compound of the inventionis administered intravenously. Saline solutions and aqueous dextrose andglycerol solutions can also be employed as liquid vehicles, particularlyfor injectable solutions. Suitable pharmaceutical vehicles also includeexcipients such as starch, glucose, lactose, sucrose, gelatin, malt,rice, flour, chalk, silica gel, sodium stearate, glycerol monostearate,talc, sodium chloride, dried skim milk, glycerol, propylene, glycol,water, ethanol and the like. The present compositions, if desired, canalso contain minor amounts of wetting or emulsifying agents, or pHbuffering agents.

The present compositions can take the form of solutions, suspensions,emulsion, tablets, pills, pellets, capsules, capsules containingliquids, powders, sustained-release formulations, suppositories,emulsions, aerosols, sprays, suspensions, or any other form suitable foruse. In one embodiment, the pharmaceutically acceptable vehicle is acapsule (see e.g., U.S. Pat. No. 5,698,155). Other examples of suitablepharmaceutical vehicles are described in “Remington's PharmaceuticalSciences” by E. W. Martin.

In a preferred embodiment, the compounds and compositions of theinvention are formulated in accordance with routine procedures as apharmaceutical composition adapted for intravenous administration tohuman beings. Typically, compounds and compositions of the invention forintravenous administration are solutions in sterile isotonic aqueousbuffer. Where necessary, the compositions may also include asolubilizing agent. Compositions for intravenous administration mayoptionally include a local anesthetic such as lignocaine to ease pain atthe site of the injection. Generally, the ingredients are suppliedeither separately or mixed together in unit dosage form, for example, asa dry lyophilized powder or water free concentrate in a hermeticallysealed container such as an ampoule or sachette indicating the quantityof active agent. Where the compound of the invention is to beadministered by intravenous infusion, it can be dispensed, for example,with an infusion bottle containing sterile pharmaceutical grade water orsaline. Where the compound of the invention is administered byinjection, an ampoule of sterile water for injection or saline can beprovided so that the ingredients may be mixed prior to administration.

Compounds and compositions of the invention for oral delivery may be inthe form of tablets, lozenges, aqueous or oily suspensions, granules,powders, emulsions, capsules, syrups, or elixirs. Compounds andcompositions of the invention for oral delivery can also be formulatedin foods and food mixes. Orally administered compositions may containone or more optionally agents, for example, sweetening agents such asfructose, aspartame or saccharin; flavoring agents such as peppermint,oil of wintergreen, or cherry; coloring agents; and preserving agents,to provide a pharmaceutically palatable preparation. Moreover, where intablet or pill form, the compositions may be coated to delaydisintegration and absorption in the gastrointestinal tract therebyproviding a sustained action over an extended period of time.Selectively permeable membranes surrounding an osmotically activedriving compound are also suitable for orally administered compounds andcompositions of the invention. In these later platforms, fluid from theenvironment surrounding the capsule is imbibed by the driving compound,which swells to displace the agent or agent composition through anaperture.
